Yes with one of those controllers you could be able to do most of the playing, recording and mixing.
With linking, I meant that you can link channel 1 and 2 to be controlled together to have the recording level controlled with the knob of channel 1 and the panning between channels with knob for channel 2.
All channels can be recorded as isolated tracks on their own. And all channels can be mixed into a final stereo recording in the same time as well as output on line out.
But as dogmusic said.
If you only are looking for a solution to do live mixing and recording on a computer, a far cheaper and simpler way would be a 3 or 4 channel USB mixer which more or less will give you the same features you will use on the MixPre-6. But for several hundred dollars less.
Thanks! So if I purchase one of the controllers you mentioned, will I be able to control most or all of the touch screen-oriented aspects of the MixPre-6 like pressing mute on the touch screen after having pressed the channel fader? I mean does it replace the USB keyboard option and provide more functionality? You also mentioned that I can't combine channels 1-2-3. But can I combine channels 1-2 and then mix them with the music coming from my laptop via these controllers? It seems to me that I should limit myself to two XLR keyboards if I'm supposed to combine and control them as one separate output. Is this true?
Cheers,
